THE NATIONAL SECURITY AGENCY RELEASES
OVER 1.3 MILLION PAGES OF DECLASSIFIED DOCUMENTS
The National Security Agency (NSA) announced today that it has
declassified and released to the National Archives and Records
Administration (NARA) over 1.3 million pages of historic cryptologic
documents. The majority of the documents are new releases, but some
documents are being re-released with additional information. These
documents cover a time-frame from before World War I through the end of
World War II and will be available at NARA for public review beginning
Thursday, 4 April 1996.
OPENDOOR is a Bibliographic Index which references NSA's declassified document
releases to NARA, and as such it will continue to grow. NSA's initial INTERNET
offering is an index of 4,923 entries containing approximately 1.3 million pages
of previously classified documents from the pre-World War I period through the end
of World War II, which have recently been released to the National Archives and
Records Administration (NARA). The collection will be made available to the public
at the NARA Annex in College Park, Maryland. For the present, the INTERNET viewer
may scroll through this index to determine the location of the entry in which
he/she is interested. To help the researcher become familiar with the format of
the index, this is the way the NSA entries read:
Item Number Box Number Accession Number Date Title
----------- ---------- ---------------- ---- -----
NR1 CBBA11 103A 19431209 GERMAN PRACTICE TRAFFIC ...
We understand that while NARA will assign its own identification
tags to each file in the collection, they plan to retain the NSA Box
Number and Accession Number for cross reference. Researchers should be
aware of two things: first, the index is not arranged in date order,
and second, each entry may contain either a single page or many pages.
A list of documents released is available on the NSA Homepage on the Internet
under Project OPENDOOR (http://www.nsa.gov/programs/opendoor/narafindaid.html).
The actual documents are available for review at the National Archives at
College Park, 8601 Adelphi Road, College Park, Maryland. Research
cards are required to view the documents. Additional information about
conducting research at the NARA is available on the National Archives
Internet Website (http://www.nara.gov).
